Efficient One‐Pot Preparation of Thermoresponsive Polyurethanes with Lower Critical Solution Temperatures [PDF]

ChemPlusChem, 2021
AbstractThis work reports a simple and scalable strategy to prepare a series of thermoresponsive polyurethanes synthesized via copolymerization of dicyclohexyl diisocyanate with glycerol ethoxylate in a single one‐pot system. These polyurethanes exhibit lower critical solution temperatures (LCST) at 57 °C.

Molecular dynamics simulations evidence the thermoresponsive behavior of PNIPAM and PDEA in glycerol solutions

Frontiers in Nanotechnology, 2023
Polymers exhibiting thermoresponsive behavior above a lower critical solution temperature (LCST) undergo a coil-to-globule phase transition that has many biomedical applications, including biosensing, the control of release devices, and gene or drug ...

Using Reverse Osmosis Membrane at High Temperature for Water Recovery and Regeneration from Thermo-Responsive Ionic Liquid-Based Draw Solution for Efficient Forward Osmosis

Membranes, 2021
Forward osmosis (FO) membrane process is expected to realize energy-saving seawater desalination. To this end, energy-saving water recovery from a draw solution (DS) and effective DS regeneration are essential.

Lower critical solution temperature behavior in polymer blends: compressibility and directional-specific interactions [PDF]

Macromolecules, 1984
Lower critical solution temperature (LCST) behavior in polymer blends is shown to be the result of the compressible nature of the system, the directional-specific character of the intermolecular interactions, or a combination of both. Certain random copolymer-homopolymer blends are examples of the first possibility.

Simultaneous Adsorption of Cation and Anion by Thermosensitive Hydrogels [PDF]

MATEC Web of Conferences, 2021
Simultaneous usage of cationic and anionic thermosensitive hydrogels was shown to positively contribute to adsorption of heavy metal ions. The potential capacity for recovering heavy metal ions from an aqueous solution was enhanced by incorporating ...

Preheated Advection Dominated Accretion Flow [PDF]

, 2000
All high temperature accretion solutions including ADAF are physically thick, so outgoing radiation interacts with the incoming flow, sharing as much or more resemblance with classical spherical accretion flows as with disk flows.

Criticality and convergence in Newtonian collapse [PDF]

, 2002
We study through numerical simulation the spherical collapse of isothermal gas in Newtonian gravity. We observe a critical behavior which occurs at the threshold of gravitational instability leading to core formation. For a given initial density profile,
